Studies were conducted to determine the effects of various parameters on the magnetic properties of sintered Sm-Co permanent magnets. The standard method of fabricating the magnets consisted of arc-melting, crushing and grinding the alloy, aligning and pressing the powder, and sintering the green compacts. Results indicated that the optimum composition was 36.7 + 0.3 wt pct Sm, 63.3 + 0.3 wt pct Co. This composition was obtained by blending together Sm^Co^ and SmCo5. The maximum values experimentally obtained were Hci = 27.4 k0e, Hc = 7=510 Oe, Br = 7,810 G, and (BH)max = 15.1 MGOe. The optimum sintering temperatures and grinding times for maximum Hci and (BH)max were determined. Lowering the max the grinding temperature from 0°C to -60°C resulted in a significant increase of magnetic properties.
